YICK-FINDER MECHANISIVI FOR LOOMS.

Application filed June 3, 1

T 0 all whom it may concern:

Be it known that I, BENJAMIN F. Mc- GUINESS, a citizen of the United States, residing at Worcester, in the count of Worcester and State of Massachusetts, have invented certain new'and useful Improvements in Pick-Finder Mechanism for Looms, ofwhich the following is a specification.

M invention relates to looms, and more artlcularly to 'a pick finder mechanism for lhoms, and particularly to the class of looms of the harness is head, or (lobby, or surface, in the in which the movement controlled by a fancy through a pattern chain well known way.

The object of my invention is to provide finder mechanism of and operation, and adapted to be applied to any loom of the class referred to, and to be used in finding the pick, after the breakage or exhaustion of the filling.

The customary and well known way of finding a pick on a fancy head, or dobby loom, after the breaking or exhaustion of filling is as follows When the filling breaks throw off the shi )per handle and stop the loom in the well lrnown way. lt generally momeni'un of the loom of the shuttle without any filling, and it is necessary, in order to find the open shed at the point weaver'to leave the shipper handle of the loom, and go to .the dobby to turn back the pattern chain; after doing: this the weaver must throw back the pawl on. the ratchet take-up gear, remove the shuttle, and hold the shuttle binder out with his hand, so that the protection dagger will clear the hunter while the proper shed is being found. After replacing the shuttle in its proper box the weaver has to let back the c oth. by releasing the holdfast pawl on the luliehp, and

l beams, bringthe lay up in the from of! the loom, and turn the take-up pear Ullllll lay wil now be pushed back to a point where: the loom can be started wilnout fear -of banging off, and the weaving can be proceeded with exhaustion that in picking the loom over without at until the next breakage or of filling: it often happens Specification of Letters Patent.

dagger has reached the buntenq chain to run bz-ickward, and the runs Patented Feb. 23, 1909 905. Serial No. 264,224, v I

shuttle, the weaver lets go of the "shuttle binder before the end of. the i'rotection I 'l he result of this is that the dagger strikes thehunter and the 100111 bangs oil. I a :1

It is obvious that the method of finding the pick .above described is slow and. 001m plicated, and entails unnecessary :wear and tear on the loom. With my improvements it is possible to find the pick without leaving the shipper handle, and without touching the take-up, and without any wear and tear on the loom.

In my improvements, I provide, preferably close beside the regular shipper handle, an auxiliary handle, or lever, preferably so constructed and located that it may be pulled on by the weaver, either separately, or bythe same movement which shipper handle. My auxiliary handle is connected with the ordinary filling stop motion, so that on the breaking or failure of the filling said auxiliary handle and the regulnrhandle are thrown off at the same L'lBlG, The throwing off of the regular handle stops the loom, and the throwing off of the auxiliary handle, connected with the pick mechanlsin, the reverse mechanism of t e pattern chain mechanism, and the take-up mechanism,

operates automatically to move the picking shoes from under the picking rolls, toiirinove the slidingclutch of the pattern chain mechanism, and to lift the pawl on the ratchet on the take-up gear. After this operation, in order that the weaver may find thepiclr, it is only necessary to pull on the regular handle, and run the loom pick by picknntil the proper shed is founo. It is unnecessar to remove the shuttle ,because the piokingsfiocs have been moved out of the path of the picking balls, and the loom will not pick. i It is unnecessary to turn back the pattern chain, because the movement of the clutch of the pattern chain mechanism causes the pat-tern n the indicator fingers are prefcraoly madeof such a shape that the )roper harnesses will always be on led instantly when theloomis stopped by the breaking of the filling, and when the loom is started up again after'finding the pick. is unnecessuryto throw back the )awl on the take-nil, because the pawl is lifted automatic'ally whhn the loom stops. After the lost pick has been foundthe loom may be starteil up at once pulling on both handles, the regular handle, and the auxiliary handle. I have also adapted my improvements to be applied to a loom having dro shuttle boxes, either at one or both 5. en s. In this class of looms it is necessary to reverse the bolt pattern chain, and the multiplier pattern chain, and to accomplish this I provide the indicatorlevers on the box pattern chain and multiplier pattern chain,

with'sliding runs which are controlled by the same mechanism which reverses the pattern chaln mechanisms. By means of the sliding runs on the indicator levers, I prevent the loss of a pick, as will be hereinafter fully described.

In case anything should catch in the gears which drive the pattern chain mechanisms, I provide a give-way sprin on the shaft beneath the dobby.

the picking ball being down prevents the picking shoe from moving back into its place at once, I rovide a spring, so that the auxilfiary hand e may be pulled on at the proper point, and the picking'shoe will move into its place as soon as the picking ball is moved out of the way. By a similar arrangement the sliding clutch of the pattern chain mechanism also moves in at the proper point. It is impossible for the clutch to catch in both gears at the wrong time, on account of the cam shape of the engaging surfaces of the clutch members, which cause the clutch to be pushed away from one ear and into the other ear. On the midd e of the sliding clutch is an annular ridge, which has an extension atone point, which will extend on one side or the other of a stationary pin, if

the auxiliary handle is pulled on in the wrong place, and prevent the clutchfrom changing from one gear to the other at the wrong time. I

I have only shown in the drawings detachcd parts of a looin having my improvements applied thereto, sufficient to enable those skilled in the art to understand the construction and operation thereof. The parts of the loom shown in' the drawings with.

"which my improvements are combined are of well known construction and operation, and

therefore do not require to be fully described herein. Referring to the drawings:Figure 1 is 55 cross section, through parts of a loom, showing the loom side on the left hand end of the loom, with the regular shipper .handle, and.

my auxiliary shipper handle, and mechanism connected therewith, and also showing the to pick mechanism. Fig, 2 is an end view of as is a cross section through partsof a loom,-

some of the parts shown in Fig. 1, looking in the direction of arrow a, same figure. The lay-sword, lay, crank connector, and crank shaft are not shown in this figure. Fig. 3

This wi I prevent slipping. '20 of. gears and will render it unnecessary to time thepattern chain over again. (then theloom is started up after picking out, and

showing the opposite end of the loom from that 'shown in Fig. 1, and showingthe dobby driving mechanism, the'pick mechanism, and the take-up mechanism. Fig. 4 is a rear view of the parts shown in Fig. 3, looking in the direction of arrow 1), same figure. Fig: 5 is a lan view of a box pattern chain and multiplier mechanism of well known construction, not shown in the other drawings,

and a part of the dobby mechanism, and also inder is moving forward, in the direction indicated by arrow 11. Fig. 10 corresponds to Fig. 9, but shows the position ofthe dobby fingers when the cylinder is moving backward, in' the direction indicated by arrow 2. Figs. 5.to 10 are shown on an enlarged scale.

In the accompanying drawings, 1 are the loom sides, 2 the lay-swords pivotally mounted at their lower ends, 3the lay-beam,

connected through crank connectors 4' with the crank shaft 5. Only one crank connector 4 is shown.

6 is the breast-beam, 7 is the bottom shaft having the picking arms 8 fast thereon, at opposite ends of the shaft; and carrying the picking balls 9, adapted to engage t e picking shoes 10, fast on the picking shafts 11.-

On the crank shaft 5 is fast a gear 12 which meshes with and drives a ear 13,

mounted on a stud 14, see Fig. 3. evolving with the gear 13 is a bevel gear 15, see

Fig. 4, which meshes with and drives .a bevelv gear 16, fast on the lower end of an upright shaft 17, mounted in suitable bearings 17 On the upper end of the upright shaft 17 is a bevel gear 18, which meshes with and drives a bevel gear 19 on the horizontal shaft-'20,

mounted in suitable bearings 21, seeFig. 3. The bevel gear 19 is yieldingly secured to the shaft 20, in this instance,by a spring actu- U ated clutch device, see Fig. 3, comprising a collar 22 having a projection 22 thereon, to enter a recess in the hub 19 of the bevel gear 19, and a spring 23, extending between a collar 24 fast on the shaft 20, and the clutch collar 22; By means of the clutch attachment of the bevel gear 19 to the shaft 20, the gear 19 can be turned without turning the shaft 20. The shaft 20 has on its inner end a bevel gear 25, which meshes with two bevel gears 26 and 27, see Fig. 4, both loose on a shaft 28, mounted-in suitablebearings 29, and carrying a' worm 30, adapted to mesh with and drive the worm gear 31, on the shaft 32 of the dobby pattern chain cylinder '33, see Figs. 4 and 5.

in Fig. 5 shown in addition to the (lobby pattern chain mechanism shown in Figs. 3 and 421. box pattern chain mechanism and a multiplier mechanism, of ordinary construetion and operation, and similar to the pattern mechanisms combined with the dobby pattern chain mechanism, shown and described in U. S. Letters Patent, No. 617,291). A gear 34 on the end of the extended shaft 28, meshes with and operates a gear 35 on the end of a shaft 36, which carries two pin Wheels 37 and 38, which are adapted to be moved into engagement with and operate two star wheels and 40, one connected with the multiplier pattern chain cylinder 4], and the other with the box pattern chain cylinder 42, all in the usual and well known wav.

' All of the above mentioned parts maybe of 't'he usual and well known construction in the class of looms referred to.

' I will now describe my improvements.

Along side of the regular shipper handle 43, pivotally mounted on a stud 44, and

having a downward extension 43 thereon,

adapted to en age the shipper lever, not

shown, to stop the loom, in the ordinary way,

is my auxiliary handle 45, having a hub 45', see Fig. 2', fast on the end of a rock shaft 46 which extends across the loom under the breast-beam, and in this instance at the rear thereof, and is mounted in suitable bearings to have a rocking motion.

In the path of movement of the auxiliary handle 45 extends a knock-off lever 47,

)ivotally mounted on a stud 48 on the breastbeam, see Fig. 2, and connected with a slide 49 carrying the filling fork 50 having the filling feelers 5] thereon, see Fig. l, for detecting the l'n'caking or absence of filling, in the usual and cell known way.

Fast on; the rock shaft 46, just inside of the loom frame, is the hub 52 of a lever 52, carrying a pin 53, on which is pivotally mounted the upper end of a connector 54, see F ig. 2. The lower end of the connector 54 extends through a boss 55"011 the upper end of a link 55, and is yieldingly eonnnected to said boss 55 by a spring 56 encircling the lower end of the connector 54, and extending between a collar 57, on the ion er end of said connector and the boss 55, see Fig. 1. The lower end of the link 55 is pivotally attached to the lever 58, see Figs. 1 and 2, which is fast on a rocking shaft 52) mounted in suitable bearings 59. The opposite end of said shaft 59 has fast thereon a lever (it), see Figs. 1 and 2, -which has a slot tit) thcrcin, into \ahich extends .1. pin (31 on a collar oi fast on a rod (52, vhich rod is pivotally connectcd at each end ith a plate (323, sec l igs. I3, nil-'1 4, "the h has a pivotal bearing ill a stand (34 secured to the loom frame, and has secured thereto the rear end of the picking shaft ll, carrying the picking shoe it), see. Figs. .2 and 3, to move both picking shafts, and cause. the picking shoes thereon to move out of the path of the picking balls 9, as sl'iovxn by broken lines in Fig. 4, in the usual and clllumvrn vny. (in the obhosite end of the shaft 46, and at the oppr-site end of the loom, see Fig. 3, is fast the upper end of a lever 6."), hich lever carries a pin (36 extending into the slo. 437' in the upper end of a lever (37, pivoted on a pin (3%, and having a shield extension (37 thereon, ehich is adapted to extend under the side projection tit) on the engaging end of the pawl fiQflIliltli operates the ratchet \z'heel of the take-up mechanism, being held in yielding engagemcnt therereith by a spring 71, and operated through an arm 7'2 fast on a rock shaft 73, in the usual v. ay.

The cod of the lever 5 is connected, through a connector 74, ith one arm of an angle lever 75, pivoted on a stud 76 on the loom frame, see Fig. 3. The other arm of the angle lever is pivotally connected v. ith a vertically moving bar 77, which has two bosses 77 thereon, through which loosely extends a rod 78, which is connected with said bosses, in this instance through two springs 7 t) encircling the rod 78 and having a bearing between the bosses 77, and a collar 78 fast on said rod 78, seeFig. 4.

The upper end of the rod 78 is i-votally connected with one arm of an angle ever 80, see Fig. 4, having a hub 80, see F ig. 3, pivotally mounted on a stud 81, secured to the loom frame. The other arm of the angle lever 80 has a yoke-shaped or forked end 80 thereon, see Fig. 6, which receives an annular ridge 82 on the clutch collar 82, splined to slide on and turn with the shaft 28, see F ig; 4. The collar 82 has projections 82 on its opposite sidcs, which are preferably inc-lined oi cam shaped, and are adapted to be moved into engagement with projections 26 and 27, also' referably inclined, on the hubs of the beve gears 26 and 2*], to clutch one or the other of said gears to the shaft 28, see Fig. 5, to cause said shaft to turn in a forward or backward direction, in the usual and well known way. By means of the incline or cam shape of the clutching surfaces, the clutch 82 will be forced away from onegear into clutch with the other, and vice versa.

It will be seen, that the movement of the auxiliary or operating handle or lever 45 to rock the shaft 46, will, through lever 65 and lever (57, move the pawl (it) out of e1 .gage ment with the ratchet wheel 7t) of the takeup mechanism, and will also, through cmtncctor 74, angle lever 75,-bar 77, rod 7%, angle lever tit), and clutch collar 82, cause the shaft 28 to rotate in a reverse direction, and reverse the movement of the pattern chain mechanism, Figs. 3 and 4.

On the clutch collar 82,1 preferably provide, on the annular ridge S2, at one point, an extension 82, see Fig. 7. Said extension 82 will extend on one side or the other 5 of a pin 83 on the shaft .20, see Fig. 5, and prevent the clutch from moving endwise on the shaft 28 and changing from one gear to the other, as 26 to 27, or vice vcrsa, at the wrong time, in case the auxiliary handle 45 1o is pulled on at the wrong time, thus preventing a mispick. i

In case my improvements are used in connection with a box patt,crn chain and a multiplier mechanism in addition to the (lobby mechanism, the forked end of the angle lever 80 will have a pin 84 thereon, not shown in F ig. l, which is pivotally connected, through a link 85, with a pin 86, see Fig. 6, on a lever 87, having a hub 87 pivotally mounted on a stud 88 secured to the frame, see Fig. S. The lever 87 carries a pin 89, which extends into an annular recess 90"iii the hub 90 of a cam 90', splined on the shaft 28, see Fig. 6. The cam 90 has oppositely extending cam surfaces 90 thereon, see Fig. 8, which extend between, and are adapted to be moved into engagement with one or the other arm of two cam arins91, see Fig. 8, having a hub 91 piv otally mounted on a stud 92, see Fig. 6.

A cross-head 91" on the upper end of the longer cam lever 91, see Fig. 5, has )ivotally attached thereto one end of two links 93. T he opposite ends of the links 93 carry a rod 94, which extends into recesses in the sliding runs 95 on the indicator levers 96, which ex-- tend over the pattern rolls orsurfaces 97 on the box pattern chain cylinder 42, and the multiplier pattern chain cylinder 41, see Figs. 7 and 8. Through the movement ofthe cam levers 91, links 93, carrying the rod 94, and i the runs 95, a proper indication ofthe pat tern chain is obtained, While finding the pick, or after startingjthe loom again. When the loom is running normally, the runs 951011 the indicator levers 96 will be in thepositio'n shown in Fig. 7, the pattern cylinder 42- rotating in a direction from right to left.v When the pattern chain mechanisms are reversed, the slidin runs 95 will be BO moved into the position s own in Fig. 8, and

the pattern cylinder 42 will be rotated in an o posits direction, or from left to right, and

' tl ie first movement of the pattern cylinder 42 a reverse direction, will through the osition of the runs 95, operate the indicator evers on which said runs" are mounted, so that there will always be a proper indication of the pattern chain without any loss of a pick, as will be well understood by those skilled in the art. The sliding runs 95 are a plied to each box indicator lever 96,-a1rd also to the indicator lever 96 of, the multiplier pattern chain, shown at the left in i 5. ln order to have the proper indication of the harnesses, by the (lobby fingers or levers 99, which extend over the (lobby pattern chain cylinder 33, shownin Figs. 9'and 10,

made with specially shaped runs thereon,

each linger or lever 99 having two runs 99, and 99 thereon, and a recessed portion 99' intermediate said runs, so that at the for ward movement of the pattern chain cylinder 32%, with a double index pattern chain thereon in the direction of arrow (1, Fig. 9,

the harness call will be operated at a point 99 ol the dobby finger. \Yhile in therevcrsc motion of the pattern cylinder 33, in the direction of arrow e, Fig. 10, the harness call will be operated ata point 99". The pattern pins 33, intermediate the two *oinis 99 and 99, will n t touch the (lobby mgers or levers 99, said fingers bein recesser at their middle parts at 99, 'as s iown.

he form and relative location of the engaging points 99 and 99'. ,and the timeof movement oi the knives or hl'ter blades, not shown, of the dobby mechanism, is such,

that in the revolution of the dobby pattern chain cylinder 33 in a forwarddirection, as indicated by arrowd Fig. 9, a pattern pin 33', at the right, will inst engage the projection 99 on a lever99 nearest'the pivotal support of said lever, and will raise the lever, and

then pass out from under the projection, while the contiguous pattern pins 33, at the center in Fig. 9, willpass into the, recessed portion of the lever, and the next pattern pin 33, at the left,...will pass under and engage the projection 99 farthest from the pivotal support of the lever, and will raise said lever at its inner end, as shown in the case of'tlle second lever in Fig. 9, to call for the harness desired. The raising of. the lever 99'by the first pattern pin 33 passing under the projection 99 on said lever is so timed, 'that'it will not cause anyoperation of the' mechanism'to call a harness, for the reasonthat at the left, will lirstengage a projection 99 on a lever 99 farthest from the pivotal'support of said lever, and willraise the lever, and then 1 ..ss out from under the projection, while the contiguous pattern pins 33, at the center in Fig. 10, will pass into the recessed portion of the. lever, and the next pattern pin 33 at the right, will pass under and engage the projection 99 nearest the? pivotal support of the lever, and will raise said lever at its inner end, as shown in the case of the first lever in Fig. 9, to call for the harness desired. The raising of the lever 99, by the first pattern pin 33, at the left in Fig. 10', passing can projection 99' on said lever 99, is a-tgit will not, cause any operation "of theemechanism to call a harness, for the construction of my improvements may be varied if desired.
